3 dead, including gunman, after mass shooting at Madden video game tournament in Jacksonville, Florida

Three people, including the gunman, were killed in a mass shooting at a video game tournament on Sunday in Jacksonville, Florida.

Jacksonville police confirmed nine people were shot and two others were injured.

Officials identified the gunman as 24-year-old gamer David Katz from Baltimore, Maryland.

The shooting comes two days after a gunman killed one person and left two injured at a high school football game in Jacksonville.

Three people, including the gunman, were killed in a mass shooting at a Madden NFL video game tournament in Jacksonville, Florida, on Sunday afternoon.

Police said 11 people were injured. Nine of them suffered gunshot wounds. Several of the injured were in stable condition Sunday evening, and one of the wounded, who suffered multiple gunshots to the chest, was in serious condition, hospital officials told CNN.

Authorities identified the gunman as 24-year-old gamer David Katz from Baltimore, Maryland. He died from a self-inflicted gunshot wound, police said.

As part of the ongoing investigation, heavily armed FBI agents on Sunday night entered a Baltimore-area townhouse that belongs to the gunman’s father, the Associated Press reported.

Katz was a known gamer and appears to have won the the Madden Bills Championship in 2017.

A recording of the Twitch live stream shows two competitors playing the game before what appeared to be a red laser appeared on the sweatshirt of one of the gamers. The image disappeared as the gunfire erupted.

The shooting comes two days after a gunman killed one person and injured two at a high school football game, which Florida Sen. Bill Nelson referenced in a tweet, writing “Word of another tragic mass shooting in our state brings shock and outrage.”
